Title: Door guide for door frame - with tension elements for simple assembly on site in counterbored holes in rail
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: F16B19/10
Filed: 1973-06-07
Abstract: The guide is fastened by screws to the hollow profile of a door frame. The screws carry tension elements, which are held in counterbored holed in the rail. Elements and screws pass through bores in the face of the hollow profile. When the screws are tensioned, the elements form abutments, engaging behind the profile face. Each element consists of a load sleeve with a passage bore for the screw, and a threaded tension core. The sleeve is located between the cone and the screw head, and accommodated tightly in the counterbored hole. The bore in the profile face corresponds to the external sleeve diameter. The tension cone has a thin walled insertion cone, and a steep expansion cone.

Title: Wire wrapping tool support - has vee notch blockable by slider actuated by electromagnet for manually guided tool
Inventor: PROKASKY NORBERT
IPC: H05K13/06
Filed: 1973-07-06
Abstract: A support for the manually guided tool of wire wrapping machine prevents the application and operation of the tool during the movement of the support into a new wrapping position and also on turning points where no wrapping is desired.

IPC: H04N9/86
Filed: 1973-12-21
Abstract: The colour television signal contains a luminance component, three colour different components and a reference component. Signals are coded in the three line sequential of specified form. These signals produce the luminance signal. A converter is connected to the signal source and controlled by the reference component which converts the above signal into a form suitable for application to a colour t.v. receiver.

Title: Capacitor cover plate with overpressure release - has sealing plate pushed into cylindrical space to actuate wire shearing levers
Inventor: KUNERT WERNER
IPC: H01G2/14
Filed: 1974-01-09
Abstract: The capacitor cover plate has an overpressure protection for shearing off of the contact wires. The overpressure generated in the capacitor housing acts on a sealing plate so that it is pressed into a special cylindrical space. This motion actuates shearing levers into motion which results in shearing off the connecting wires. The levers may be replaced by suitable devices, such as shearing sockets, eyelets etc. Pref. the sealing plate is provided with sealing flaps of any appropriate design to prevent pressure penetration into the cylindrical space and to define the pressure moment required for the protective operation.

Title: Ceramic item handling system - has travelling fork transferring from incoming track to gratings on truck
Inventor: GROSS KARL
IPC: B65G49/08
Filed: 1974-04-10
Abstract: The mechanism loads and unloads drying trucks with rows of clay tiles, there being grating shelves in the trucks, which are raised and lowered by a platform. A feed track for the rows of tiles leads direct to the platform, to which a fork, rising and sinking and travelling, transfers them, depositing them on the gratings by vertical and horizontal movement. On one side, the space between the grating bars can be unobstructed, to allow insertion of the fork prongs. The design gives rapid and gentle handling, without risk of distortion in the process.

Title: Controlled transistor rectifier with feedback - has series-connection of resistor and collector-emitter path of transistor coupled to transformer secondary
Inventor: GANZER ERICH DIPL ING
IPC: H02M3/338
Filed: 1974-06-20
Abstract: The controlled transistor rectifier operates according to a blocking transformer principle. The feedback voltage tapped at a feedback winding of the transformer for the control of the switching transistor is dependent on a measuring voltage, proportional to the output voltage. This measuring voltage is tapped from an auxiliary coil of the transformer. A series connection of a resistor (R5, R8) and the collector-emitter path of a transistor (Ts4, Ts5), with additional control by an amplifier (Rg), is connected to a secondary winding (IV, III) of the transformer (Tr) via a rectifying circuit (Grl1C3; Gr2, Cr). The rectifier circuit diode (Gr1, Gr2) is rendered conductive during the blocking interval of the switching transistor (Ts1). The series connection of the resistor and collector-emitter path forms a parallel preload resistance.

Title: Vehicle steering rack with vibration packing - uses thicker central part of rack for secure support for normal travel
Inventor: DIETRICH GEORG DR ING
IPC: F16H55/26
Filed: 1974-12-10
Abstract: The rear of the steering rack (3) is provided with a pressure pad (5) held against the rack by a spring (4) and by packing washers (6). In order to minimise steering vibration the rack is profiled so that the thickest section is in the middle, tapering to the thinner ends.

Title: Blow moulding molecularly oriented thermoplastic containers - to ensure uniform wall thickness from blanks extruded and heated unevenly
Inventor: BERGGREN LORING JOHN
IPC: B29C49/42
Filed: 1974-11-20
Abstract: Hollow articles are produced from extruded blanks of thermoplastic material which are symmetrical around an axis and are closed at one end. The blanks are at a temp. which at least in parts in higher than that required for molecular orientation, and they have circumferential zones of different thickness, between which the temps. are also different. The temp. of these zones is reduced, whilst maintaining the differences in temp. to a value at which molecular orientation can be achieved, and these zones of different thickness are expanded to a different degree so that they lie against the walls of the mould. The wall thickness of the thicker zones is reduced more sharply than that of the thinner zones, so that the object produced is given a more uniform wall thickness. Risk of bursting when filled with a pressurised liq. is reduced.

Inventor: ELLIS RAYMOND
IPC: A63B6/00
Filed: 1975-04-17
Abstract: This floor mat for gymnasts forms a shock-absorbent, insulated base of rubber or plastic and consists of twelve identical, rectangular mats (1-12) which form the main mat surface with a number of edge mats. The central mats are fitted together by means of 'teeth on each side, which are arranged so that the teeth on each side of the mat dovetail with the teeth on the neighbouring mat. The edge mats covetail together round each side of the main mat each having one straight edge to form the edge of the mat with four rounded corner pieces. This method produces a mat, which is easily and quickly assembled so that the parts do not slide apart while in use but can be quickly broken down to small, lightweight easily transportable parts.

Title: Overload safety clutch with slipping rollers - reduces roller wear by relieving spring load during torque overload
Inventor: MAURER RUPRECHT DIPL ING
IPC: F16D43/206
Filed: 1975-04-23
Abstract: The main patent refers to an overload safety clutch in which an assembly of belleville washers provides an axial load to keep rollers (2) in grooves (4) in the driven member. When the clutch slips, the rollers (2) are subject to heavy wear as they roll in and out of successive grooves (4). The addition to the patent secures the ring (23) which carries the belleville washers with a row of bells fitting in slots. Under overload these balls roll out of the slots allowing the ring (23) to move to the right and remove the axial load from the rollers (2) so that they are no longer forced into the grooves (4).

Title: Screwed connection for smooth tubes - with internal rings inside threaded sleeve and tightened by outer union
Inventor: KAETHNER VOLKHARD ING GRAD
IPC: F16L19/06
Filed: 1975-06-04
Abstract: A screwed connection for smooth or hard tubes consists of a threaded sleeve and union with a pressure ring between then inside an extension of the sleeve. The sleeve fits round the end of the tube and the end of the latter lies against a flat shoulder in the sleeve; a sealing ring and a pressure ring are pushed together in the radially extended part of the threaded sleeve on the tube. The pressure ring is pressed against a shoulder in the sleeve and the sealing ring is so pressed into the sleeve by screwing up the union that the sealing ring is forced into the tube and forms a groove in it. The connection can be sunscrewed, otherwise it produces a tight joint even on a rough tube or if repeatedly unscrewed. The method is partic, suitable for thin tubes.
